Controlling Devices Unit 5E Making an
Advertising Board.
Instructions for working away from the computer
with Valiant Control Console and Cambridge
Brainbox Primary Electronics Kit.
2
Devices all around us are controlled through
Direct Instructions.

• Single Instructions -
• Barrier in Car Park
• Exit Door
• Sequence of Instructions-
• Pelican Crossing
• Washing Machine

How Electricity Works.

• Electricity is a flow of electrons.
• A circuit will not work if there is a break in
  it.
• The electrons can not flow.
• An electric current flows between two points
  because there is a difference in voltage.
  (energy level)
• The positive terminal of a battery is at a High
  Voltage level.
• The negative terminal is at a
• Low Voltage level.

4
An Electric current behaves like the ball on the
piece of wood shown below.
5
The current will flow from high to low just like
the ball.

What happens if both children raise their ends?

Technical Vocabulary

• Electrons
• Circuit
• Output
• Voltage (energy level)
• On / High /
• Off / Low / -
• Time

8
Using Electricity worksheets.

• You will have completed the Using Electricity
  worksheets with the Electronics Kits.
• Now have a look at Using Electricity 5.
• Make sure you have the Working away from the
  computer sheet.

9
Setting up Control Console

• You will need a clear desk near to a plug socket.
• Plug in the power lead to the Console.
• Plug into the wall power socket.
• The Console will make a noise when it is turned
  on.(Do not turn it on until you have connected
  your outputs.)
• When you have finished do not take the lead from
  the console just turn off the wall socket.

10
Connecting your circuit

• Connect one red plug with crocodile clip on, to
  OUTPUT 1. Use a screwdriver to tighten.
• The second to the green socket next to it.
• Avoid unplugging these once they are connected as
  they will break if not carefully removed.

11
SAFTEY FIRST

• DO NOT connect an external power supply (mains or
  battery) to any of the Console terminals.
• DO NOT connect a Red Output directly to a green
  Ground Terminal.
• DO NOT connect a Red Output directly to another
  Red Output.
• DO NOT be responsible for breaking the equipment.

12
Replacing the battery.
Remove the battery and connect the crocodile
clips to the metal studs.
13
Turning the bulb on.

• Instead of typing the instructions into a
  computer, we are keying them into the Control
  Console.
• Start with the OUTPUT you want to control.Then
  select either-
• HIGH/ (ON)
• LOW/- (OFF)

14
Then you need to say how long for.

• Time
• Then a length of time.
• 1 1 tenth of a second.
• 10 1 second.
• e.g. 1 10

OUTPUT

15
Next you can add another circuit.
Remember to key in the correct OUTPUT!
16
Key in instructions to first turn on your light
bulb, then your fan.
17
We are going to make an Advertising Board using
an Electric Circuit. We are going to include
three factors.

• Light.
• Colour
• Movement.

18
Planning and making your board.

• Either lay a piece of paper over your circuit and
  mark where you need your holes
• Or use the planning sheet.
